Dunno about there, but adopting babies almost impossible in US. There simply is not enough to fulfill the need.
I have some relatives that tried to "save the world" as they put it, and adopt kids (not babies). These are very intelligent parents, one has masters in nursing, the second a masters in mathematics and education. The kids were not emotionally stable when they got them at ages from about 8-10 years old. 30 years later one killed himself after losing total visitation rights to his kids, a second has also lost total visitation rights and pretty much hangs with teenagers doing drugs, a third has never been able to keep stable relationships and therefore has never had a family. As a control, their own biological kids turned out great. They also say with hindsight they would not do it again.
Aye, correct. In the US, there would be many Americans who would gladly adopt from within the US if they could adopt a BABY. The problem is that couples seeking to adopt are hard pressed to find BABIES to adopt, the demand far exceeds the supply, as you have stated. This is largely due to the fact that the vast majority of children in the US foster care system were no longer babies by the time they entered the foster care system. As you pointed out, those big hearted couples who do adopt these older children often end up with a lot of extra emotional and legal baggage that comes with the children, especially if the adoption is not a CLOSED adoption... all in addition to the other risks that come with adopting any child (disabilities, mental illness, birth defects, etc.). This is why you find couples going outside the foster care system to adopt within the US, like in the movie Juno.
I am a product of a foreign adoption by American parents back in the 80s. I was only an infant when I was adopted from Korea. My adoptive parents, the only parents I have ever known and care to ever know, largely decided to adopt from Korea because of the ease of adopting a BABY from there. Back then, there were a lot of stigmas and prejudices (and probably still are to a lesser degree) because of a historical emphasis on blood lineage in Korean society, making it difficult to find even Koreans willing to adopt other Korean babies.
I am grateful every day of my life for the opportunities I have been afforded because my birth mother had the strength to put me up for adoption. Sometimes I ponder what my life would have been like had my birth mother kept me... I for sure know that I would not have the education, financial stability, career, etc. etc. that I have today.
